Accepted name: carboxylate reductase (NADP+)
Reaction: an aromatic aldehyde + NADP+ + AMP + diphosphate = an aromatic acid + NADPH + H+ + ATP
Other name(s): aromatic acid reductase; aryl-aldehyde dehydrogenase (NADP+)
Systematic name: aryl-aldehyde:NADP+ oxidoreductase (ATP-forming)
Comments: The enzyme contains an adenylation domain, a phosphopantetheinyl binding domain, and a reductase domain, and requires activation by attachment of a phosphopantetheinyl group. The enzyme activates its substrate to an adenylate form, followed by a transfer to the phosphopantetheinyl binding domain. The resulting thioester is subsequently transferred to the reductase domain, where it is reduced to an aldehyde and released.
